Sorry, should have said it at the first place. It's 1.4.0-release.

May be. But it's a result of the default configure at FreeBSD.

Do you mean libusb at the sources?.. It is definitely there.

I see. Does that mean that *bsd are not more supported by default?
I mean that the upcomming release will not contain usb code for *bsd?

Actually I'd love to use your code/drivers but I failed to build
1.4.0-release at FreeBSD )until I just copy the system's libusb.a
to your SRC/libusb directory). Then and only then the build succeeded.

Thanks, that was helpful.
